The present invention relates to an aeration nozzle and a liquid fertilizer manufacturing apparatus using the same, and more particularly, to supply oxygen to a fluid including organic waste such as livestock manure, and to collect and condense ammonia nitrogen generated from the oxygen-containing organic waste. It relates to a fluid oxygen supply nozzle for producing a liquid ratio by using the same and a liquid ratio manufacturing apparatus using the same.

Livestock wastewater contains high concentrations of pollutants that are hundreds of times more than ordinary household sewage, which makes it difficult to treat them with certainty and economically as a general wastewater treatment facility. Solids, organic matter and nitrogen concentrations in livestock wastewater not only hinder the efficiency of the water treatment process but also make it difficult to maintain the facility.

The livestock waste contaminates groundwater, causes fatal health, hygiene and environmental hazards to humans and animals, spreads odors and pests, inhibits animal growth, increases livestock mortality, and makes treatment difficult. Increasing costs are becoming social issues.

Livestock wastewater generally contains thousands of ppm of high ammonia nitrogen. In the case of such a high concentration of ammonia nitrogen, biological treatment is limited and high ammonia nitrogen concentrations have been reported to inhibit the activity of the nitrogen-removing microorganism itself. Therefore, as a solution, a method of lowering the concentration by diluting the wastewater and a physicochemical denitrification method are used. There are many physicochemical denitrification methods, but in the case of air stripping, the material transfer triggered by the principle of the equilibrium of concentrations of substances is the key mechanism.The higher the concentration of ammonia-containing wastewater, the better the application and the faster the treatment. It has However, in spite of various advantages, there are problems due to secondary treatment of deaerated ammonia gas, which makes it difficult to apply the site.

The organic waste contained in the first tank 200 is pumped to the second inlet nozzle 723 at a high pressure by the second pump 710. The organic waste pumped to the second inflow nozzle 723 is discharged into the first tank 200 through the second discharge nozzle 724 after passing through the plurality of third unit nozzles 727.

At this time, the organic waste passes through the plurality of third unit nozzles 727 at high speed by the second pump 710, and a negative pressure is generated between the plurality of third unit nozzles 727 due to the flow rate of the organic waste. Oxygen is introduced between the plurality of third unit nozzles 727 through the second suction port 725 and mixed with the organic waste. Through this process, the first aeration nozzle unit 320 may discharge the organic waste and air by mixing at high speed.

As mentioned above, the second aeration unit 700 supplies oxygen to the organic waste flowing from the second tank 600 to the first tank 200 to primarily mix the organic waste and oxygen, so fermentation efficiency of the organic waste is increased. Improve.
